Good value Started with one dew heater, then two now four. Works well for my ever expanding set up. Rapid service from HT (29/01/2024) DaveP - Chester
Very good. Very fast delivery, and a very good heat controller, thank you. (21/01/2024) Michael - Ashford Kent
Works well Encountered dew problems with my new hobby, this and some dew heaters have solved them. (16/11/2023) Paul M - Kidlington
Four heater controls that work independently, so I can control each dew strap. works with all dew straps with rca phono pins. Thought the red led in cigarette plug was a bit too bright, maybe a larger resistor needed to make it dimmer, but this is nitpicking. Recommended. Fast despatch too! (10/04/2023) M culver - Kent
Va;ie for the money Bought this to power/control my Kendrick dew heathers and works a treat. Works as good as any of the expensive makes and at a decent price. Very impressed and a good buy. (10/12/2021) Dave - Louth, Lincs
Well made unit…. The unit powers my three Kendrick tapes to full power with ease. The power lead could be a bit longer. The knobs are a little small for my aged fingers. The power level LEDs are strangely placed and not easy to see, but clear labelling of the knobs renders them redundant anyway. Overall, a good buy! (31/10/2021) Trevor - Fenland, Cambs.
